1782 — Congress Adopts the Great Seal of the United States

After six years of debate and multiple design committees, the Continental Congress approved the Great Seal, establishing the national emblem that would appear on treaties, passports, and official documents.

1863 — West Virginia Admitted as the 35th State

Its admission reflected the Lincoln administration’s determination to reward loyalty and weaken Confederate influence.

The measure aimed to reduce the risk of accidental war by enabling rapid, clear communication during crises. Though often dramatized as a red telephone, the system initially relied on secure teletype circuits. The agreement signaled a cautious step toward Cold War stability, acknowledging the catastrophic potential of miscalculation in the nuclear age. It also marked the beginning of a series of arms‑control and confidence‑building measures that would shape superpower diplomacy for decades.

Beyond its cinematic impact, Jaws sparked public fascination—and fear—of sharks, influencing coastal tourism and marine‑life perceptions. Its legacy endures as a landmark in American film history and a template for modern blockbuster filmmaking.

2013 — Supreme Court Strikes Down Key Part of Voting Rights Act
